ListOBIStats provides an HTML as well a CSV file containing the summary performance stats from OBIEE (Oracle Business Intelligence Enterprise Edition) by parsing the nqquery.log generated by the BI server.




It collects the following information for each Logical SQL
* Logical SQL Hash ID
* Physical SQLs and their hash id
* Elapsed Time
* Number of rows fetched
* ADFQuery XML tag if the datasource is OTBI 
  (Oracle Transactional Business Intelligence)
* A CSV file containing above data




Each Logical or Physical SQL is properly formatted and indented.
They are written to separate files and are accessible 
from the HTML results in the browser.




If the datasource is an Oracle database, 
it is possible to automatically generate the Explain Plan.
